Hore na khetho ea mokhoa oa ho hokahanya pakeng tsa valve ea serurubele le phaephe kapa thepa e nepahetse kapa che, e tla ama ka kotloloho monyetla oa ho matha, ho rotha, ho rotha le ho dutla ha valve ea phaephe. Mekhoa e tloaelehileng ea ho hokahanya li-valve e kenyelletsa: khokahanyo ea flange, khokahanyo ea li-wafer, khokahanyo ea li-butt welding, khokahanyo ea likhoele, khokahanyo ea ferrule, khokahanyo ea li-clamp, khokahanyo ea ho itšireletsa le mefuta e meng ea khokahanyo.
A. Khokahano ea Flange
Khokahano ea Flange kebelofo ea serurubele se nang le flangede nang le li-flange lipheletsong tse peli tsa 'mele oa li-valve, tse tsamaellanang le liphaephe tse phaepheng,' me li kentsoe pompong ka ho koala li-flanges. Khokahano ea Flange ke mokhoa o sebelisoang haholo oa ho hokahanya li-valve. Li-flanges li arotsoe ka holim'a convex (RF), bokaholimo bo bataletseng (FF), bokaholimo ba li-convex le concave (MF), joalo-joalo.
B. Khokahano ea Wafer
Belofo e kenngoa bohareng ba li-flange tse peli, le 'mele oa valve oaserurubele valvehangata e na le lesoba la boemo ho nolofatsa ho kenya le ho beha.
C. Khokahano ea Solder
(1) Khokahanyo ea tjheseletso ea butt: Lipheletso ka bobeli tsa 'mele oa li-valve li sebetsoa hore e be li-grooves tsa tjheseletsa tsa butt ho latela litlhoko tsa tjheseletsa tsa butt, tse tsamaellanang le li-grooves tsa liphaephe, 'me li tsepame pompong ka ho tjheseletsa.
(2) Khokahanyo ea li-socket welding: Lipheletso ka bobeli tsa 'mele oa valve li sebetsoa ho latela litlhoko tsa socket welding,' me li hokahantsoe le pipeline ka socket welding.
D. Khokahano e khoele
Mahokelo a likhoele ke mokhoa o bonolo oa ho hokahanya 'me hangata o sebelisoa bakeng sa li-valve tse nyane. 'Mele oa valve o sebetsoa ho ea ka mokhoa o mong le o mong oa khoele,' me ho na le mefuta e 'meli ea khoele e ka hare le khoele e ka ntle. E lumellana le khoele e phaepheng. Ho na le mefuta e 'meli ea likhokahano tse kopantsoeng:
(1) Ho tiisa ka ho toba: Likhoele tse ka hare le tse ka ntle li phetha karolo ea ho tiisa ka ho toba. E le ho etsa bonnete ba hore khokahanyo ha e tsoe, hangata e tlatsitsoe ka oli ea lead, hemp ea khoele le tepi ea PTFE e tala; har'a eona PTFE tepi e tala e sebelisoa haholo; thepa ena e na le ho hanyetsa kutu e ntle le phello e ntle ea ho tiisa. Ho bonolo ho e sebelisa le ho e boloka. Ha e qhaqha, e ka tlosoa ka ho feletseng hobane ke filimi e sa tsitsang, e molemo haholo ho feta oli e etellang pele le hemp ea khoele.
(2) Ho tiisa ka tsela e sa tobang: matla a ho tiisa khoele a fetisetsoa ho gasket pakeng tsa lifofane tse peli, e le hore gasket e phethe karolo ea ho tiisa.
E. khokahano ea ferrule
Khokahano ea ferrule e ntlafalitsoe naheng ea heso lilemong tsa morao tjena. Khokahano ea eona le molao-motheo oa ho tiisa ke hore ha nate e tiisitsoe, ferrule e tlas'a khatello, e le hore moeli oa fereko o lome leboteng le ka ntle la phala, 'me bokaholimo ba ka ntle ba fereko bo hokahane le lenonyeletso tlas'a khatello. Bokahare ba 'mele bo amana haufi-ufi le sebaka se tapered, kahoo ho lutla ho ka thibeloa ka botšepehi. Joalo ka li-valve tsa lisebelisoa. Melemo ea mofuta ona oa khokahano ke:
(1) Boholo bo nyane, boima bo bobebe, sebopeho se bonolo, ho qhaqhoa habonolo le kopano;
(2) Matla a matla a ho hokahanya, mefuta e mengata ea tšebeliso, ho hanyetsa khatello e phahameng (1000 kg / cm 2), mocheso o phahameng (650 ° C) le ho tšoha le ho sisinyeha;
(3) Ho ka khethoa lisebelisoa tse sa tšoaneng, tse loketseng ho thibela ho bola;
(4) Litlhokahalo tsa ho nepahala ha mochini ha li phahame;
(5) E loketse bakeng sa ho kenya sebaka se phahameng.
Hajoale, foromo ea khokahano ea ferrule e amohetsoe lihlahisoa tse ling tsa li-valve tsa bophara bo nyane naheng ea heso.
F. Khokahano e senyehileng
Ena ke mokhoa o potlakileng oa ho hokahanya, o hloka feela liboutu tse peli, leserurubele se grooved qetellonge loketse khatello e tlaseli-valve tsa serurubeletse atisang ho qhaqholloa. joalo ka li-valve tsa bohloeki.
G. Ka hare ho ithatafatsa kgokelo
Liforomo tsohle tse ka holimo tsa khokahanyo li sebelisa matla a kantle ho fokotsa khatello ea seaplane ho fihlela tiiso. Lintlha tse latelang li hlalosa mokhoa oa ho ikamahanya le ho itšepa o sebelisa khatello e mahareng.
Rela ea eona ea ho tiisa e kenngoa ka har'a khoune e ka hare 'me e etsa angle e itseng ka lehlakoreng le shebaneng le bohareng. Khatello ea seaplane e fetisetsoa ho cone e ka hare ebe e fetela lesale la ho tiisa. Ka holim'a cone ea lehlakoreng le itseng, ho hlahisoa matla a mabeli a likarolo, e 'ngoe e nang le Mohala o bohareng oa' mele oa valve o tšoana le ka ntle, 'me e' ngoe e hatelloa khahlanong le lebota le ka hare la 'mele oa valve. Matla a ho qetela ke matla a ithatafatsang. Ha khatello e mahareng e le kholo, ho na le matla a ho ithatafatsa. Ka hona, foromo ena ea ho hokahanya e loketse li-valve tse phahameng tsa khatello.
Ha e bapisoa le khokahanyo ea flange, e boloka lisebelisoa tse ngata le matla a basebetsi, empa e boetse e hloka ho jara pele ho itseng, e le hore e ka sebelisoa ka botšepehi ha khatello ea valve e sa phahame. Li-valve tse entsoeng ka molao-motheo oa ho itiisa ka botsona ke li-valve tse nang le khatello e phahameng.
Ho na le mefuta e mengata ea likhokahano tsa li-valve, mohlala, li-valve tse ling tse nyane tse sa hlokeng ho tlosoa li entsoe ka liphaephe; li-valve tse ling tseo e seng tsa tšepe li kopantsoe ka li-sockets joalo-joalo. Basebelisi ba li-valve ba lokela ho phekoloa ho latela boemo bo itseng.
Hlokomela:
(1) Mekhoa eohle ea ho hokahanya e tlameha ho bua ka litekanyetso tse lumellanang le ho hlakisa litekanyetso tsa ho thibela valve e khethiloeng hore e se ke ea kenngoa.
(2) Hangata, phaephe ea bophara bo boholo le valve li hokahanngoa ka flange, 'me phaephe ea bophara bo nyane le valve li hokahanngoa ka khoele.
